I just returned from visiting my parents in Texas and brought over 500 slides of when I was little home with me in a huge zip lock bag. Does anyone have any suggestions on a quick and easy way to view them in order to sort them short of holding them up to a light?

I use a light table to sort them. Mine is just the little portable one. They do make little slide viewers, but I found the light table adequate. Once you have them sorted you can come visit me and use the auto slide feeder with my negative scanner. It does stacks of up to 50 at a time.
